PUMP SYSTEM.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed September 2, 1913. Serial No. 787,737.

To all whom it may concern Be it known that I, FREDERICK C. Crown, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Pump Systems, of which the following is a specification.

It is the primary object of the invention to provide a pump system especially adapted for irrigation purposes, which is actuated by making use of the wind, the waves and running water for the operation of the pump. With this object in view I provide a suitable floating means adapted to be operated by wind catching fences for the operation of the pump and means for controlling the actuation of the floating means by the wind.

A further object of the invention is to be seen in the arrangement of water controlled means for making use of the force of the waves and of the running water for actuating the floating means to operate the pump.

A still further object of the invention is to provide a pump which is effectively protected against damage caused by a sudden onrush of water and tending to elevate the floating means for the operation of the pump above the normal level or to prevent a lowering of the same below said normal level if the water should suddenly fall below said level.

Other objects of the invention consisting in certain novel features of construction, combination and arrangement of parts, will be more fully described and particularlypointed out in the appended claims.

A practical embodiment ofthe invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

In the drawings: Figure 1 is a front elevation of the pumping system. Fig. 2 is a top plan view of the same. Fig. 3 is a detail view of the pump proper. Fig. 4 is a section on line 44 of Fig. 3. Fig. 5 is a detail view of the air induction valve. Fig. 6 is a fragmentary detail view of a wind fence. Fig. 7 is a sectional view of a valve on the upstroke of the pump piston. Fig. 8 is a similar view of a valve in section on the downstroke of the piston. Fig. 9 is a plan view of a water outlet controlling device.

Fig. 10 is a front elevation thereof, and Fig. 11 is a section on line 11-1l of Fig. 2.

A floating vessel, barge or pontoon, l, ballasted with any suitable material such as for lnstance sand 2 is provided with a central vertlcal post 3 and corner posts 4. Shafts 5 secured in suitable bearings 6 to said posts 3 and 4 are provided and held by said posts against rotation in said bearings. To the shafts 5 are secured by means of clamps 8 oscillating fences 7 while springs 9 secured with one of their ends to said clamps 8 and with the other to said shafts 5, tend to hold said fences in their upright position, a stop 10 being provided for limiting the oscillation of said fences. The fences serve to catch the wind from any direction and to rock the pontoon correspondingly. If how ever, the wind should become too strong, the spring 9 will yield and permit the fences to give way to the wind against the action of said spring, thus protecting the parts against breakage or injury.

Toward one side the water carrying the float is dammed in by a wing dam 12 to which are secured guides 11 between which a head 10 is guided adapted to be adjusted to the proper height by means of a threaded rod 13 held in position by a hanger 14 and a collar 15 (see Fig. 11). At one end of said rod 13 a bevel gear 16 is secured which meshes with the gear 17 carried by a horizontal shaft 18 provided with a handle 19 at its opposite free end. It is clear that by turning the handle 19 the rod 13 and with it the head 10 may be raised and lowered at will. A set screw 20 is provided in the standard 21 upon the dam 12 supporting the free end of the shaft 18, said set screw serving to secure the head 10 in its adjusted position. A bracket 22 secured to the head 10' supports a pump 23 the casing of which is moreover held in the proper position to said head by means of hoops or collars 23' suitably arranged intermediate its ends (Fig. 3). The pump 23 as shown in Fig. 4 is provided with a piston 24 consisting of two leather cups 25 with an intermediate metal plate 26. The rod 27 of the piston 24 is connected by means of pitmen 28 to an arm 29 which is pivoted with one of its ends as shown at 30. Fig. 3, to the head 10 and with the other of its ends as shown at 31. to the pontoon or floating vessel 1.

It will be apparent that when the pontoon is rocked. either by the wind blowing against the fences 7 or by the action of the waves or ing motion of the vessel from the above named causes the same will be lowered and compel the-piston of thepu-mp-23 to execute a downward stroke which will pump the water sucked on during its upward stroke through the hinged check valve provided with a suitable check valve.

Centrally to the bottom of the vessel 1 a rubber bag 35- or the like is secured which is connected by means of a pipe 36 tothe pump 23. An air check valve 38 is suitably arranged in a branch pipe 38 connected to the pump casing nearthe upper end thereof. Onthe upstroke of the; pump the valve 38 will be in the position illustrated in Fig. 7 and the air contained in; the portion :0 of the'pump 23 will be forced to, flow in the direction of the arrows, Fig. 7, into the pipe 36 and into the rubber bag 35, inflating the same and thus causing the rising of the pontoon I. On the downstroke of the piston valve I 38 will assume the position shown in Fig. 8 and the aircontained in the bag 3.5 will be exhausted as indicated by the arrows in said figure through pipe 39 totheatmosphere. As at this time no air can be drawn in'through the valve 38' the valve 40 (Fig. 5), will be drawn down against the action of the spring 41' and thus supply thepump 23-w-itha charge of air.

.,The valve 42 (Figs. 7'- and is provided with 'an extension 43 having a: squared end 44 (Fig. 3) over which a link 45 fits. This link 45 is providedwith a pin 46 (Fig. 3)

and a spring 47 is adapted to press a notch link- 48* into engagement with said pin 46. This link- 48; is pivoted at 49 to the arm 29'. From this construction it will be clear that the moment the pontoon and consequently the arm 29" start to rise, the; link 48 will pull the pin 46 and the link 45 upwardly and turn the valve42- into the position shown in -Fi'g. 7'. However, the moment the valve 42 is fully opened, a pin 50 integrally made with said valvewill strike against a shoul- (her 51 of'the'casing 38". In this manner the valve 42 will be prevented from turning farther and the link 48 will then simply slip over the pin 46. V-Vhen the arm 29 starts downwardlv the spring 47 will come into playand throw thelink 48 into engage ment with thepin 46 and turnthe valveinto the position shown in Fig; 8 and the pin 50 will strike against another shoulder" 51 and the link 48 will slip over thepin 46 without operating the valve.- The notches 52 of the link'48? are so selected that they. allow a :ver-

tical ratchet movement in both directions up or down.

The. wing dam 12, is provided with a tunn'el 53' so that the water rushing through said tunnel will exert an upwardly directed force upon the vessel 1. In its center the bottom-of the pontoon 1 is provided with an opening 55 allowing the passage of a cable 56 guided over a pulley 57 and carrying at its free end a weight 58. The opposite end of the cable 56 is fastened to a compression spring 59 and to a cover 60 closing athroat or vent 61 passing through the wing dam 62 as shown at 63' (Fig. 1). From this construction it will be clear that in case the water rushes insuddenly and raises the float abovethe normal level, the cover 60' will be lifted and the superfluous water will be made to flow oil through 63.. Whereafter,

as soon as; the level of the water returns to normal, the cover 60 will press upongits seat over the throat. 61. It is" to be understood that the weight 58' is preponderating the weight of the cover 60 and also the pressure of the water exerted upon said cover. On account oi its elasticity the cable guided over the-pulley and carrying the weight will prevent any" damage to the apparatus. or system in case the water should fall sud d'enl'y under it's-normal level.
